Turfgrass Weed Control Database

The Turfgrass Weed Control Database contains the same information
and pictures included in the Miscellaneous

The weeds are arranged alphabetically by scientific name because common
names vary and thus be inaccurate.

Prostrate Knotweed, Polygonum aviculare

Metsulfuron at 0.5 oz per acre or dicamba (Banvel, Vanquish) at 0.5 lb per acre will control prostrate knotweed. Celsius WG (thiencarbazone + iodosulfuron + dicamba) should be effective on lespedeza. There are many combination products that contain 2, 4-D and dicamba including Trimec 992 and Speedzone.
